The present invention relates to a display apparatus and operational method therefor, and an electronic apparatus, and the display apparatus according to an embodiment of the present invention may comprise: a resonance circuit unit for generating voltage by means of inductive electromotive force generated due to an external apparatus; a capacitance variance unit for varying the capacitance (Cv) of the resonance circuit unit in order to control the resonance point thereof, the resonance point having been changed due to the distance from the external apparatus; and a display panel for implementing an image by means of the voltage.

Display apparatus and operational method therefor, and electronic apparatus

Provided is a method for designing a current supply device for wirelessly supplying power to a vehicle having a current collection device. In the design method, the gap between the two adjacent magnetic poles of the current supply device is received as input and then the gap between the current supply device and the current collection device is determined based on the gap between the two magnetic poles. Next, the magnitude of the power to be supplied to the current supply device is determined based on the value required with respect to the magnitude of the magnetic field and the gap between the current supply device and the current collection device. According to the design method, current supply device can easily be designed since various functional requirements are decoupled from each other.

Method and device for designing a current supply and collection device for a transportation system using an electric vehicle

An ultra slim power supply device for supplying power to an electric vehicle in a contactless manner includes at least one power supply track buried in a road. Each power supply track includes a plate-shaped magnetic core extending along the road, a plate or strip shaped magnetic field generator arranged above the magnetic core through which an alternating current is supplied to generate a magnetic field, a plate or strip shaped insulating body positioned between the magnetic core and the magnetic field generator to isolate them from each other, and a housing for enclosing the magnetic core, the magnetic field generator and the insulating body.

Ultra slim power supply device and power acquisition device for electric vehicle

It is provided a power supply device and a power acquisition device for an electromagnetic induction-powered electric vehicle that increase a power transfer efficiency by maximizing a lateral deviation tolerance and by minimizing a gap between the power acquisition device and the power supply device while preventing the power acquisition device from colliding with an obstacle present on a road and being damaged by the collision.
